Adding RAM Sony VAIO VGC RB30 This computer has 512M RAM now using 2 of 4 RAM slots. I want to upgrade it to 2G RAM which is the max. Can I take out the 2 256M RAM chips and replace it with a single 2G RAM or do I need to do it as a pair of 1G RAM chips?

I usually browse to 4allmemory.com and let them scan the system (see "Check My System"). They can usually tell me how many slots, how much ram is installed, the max ram I can install, and will usually offer chip options at a competitive price... http://www.4allmemory.com/

Ram is installed on the bottom of the laptop. there should be a small compartment about the size as the RAM sticks. Make sure you get laptop ram as desktop ram wont fit. From there you just push on the fins of the ram to pop them up slide one out replace and push back down to lock again.

i was unable to locate the specific video for this type of computer desktop ram installation is pretty much the same on all desktops

if you're not sure if a module is right for your system, use theCrucial Memory Advisor tool for a list of guaranteed compatible modules.

first you will need to select the manufacturer from a drop down list then select your product line from a drop down list then select the model then click find it will take you directly to compatible ram also you will have an option to scan your system

you should always ask for a guarantee on the compatibilitybefore making any purchase and try to buy for working pairs if possible

the specs for your computer, it states that it is equipped with 2gb of memory 2x1gb and max at 2gb, so I doubt that any higher memory upgrade installed would work, or else it would cause your system to crash or even damage it.
